It's under /proc, not under /proc/sys so Tom H is right, sysctl is not
the right tool. Sorry about that, I didn't read carefully enough.

Look at the existing upstart scripts in /etc/init, copy one of the
simple ones to a name of your choosing, e.g colin.conf, and change it to
set that control variable you found. You don't really need a "stop"
task. Something like this (untested!):

   # colin

   description     "whatever you like"

   start on runlevel [2345]

   task

   script

   echo disabled > /sys/devices/pci0000:00/0000:00:1a.0/power/wakeup

   end script

The system will then set the variable for you by running the script on
startup.

Regards, K.
